ST. PETERSBURG, Mach 28. /TASS/. Russia’s Pacific Fleet will get six Project 636.3 ‘Varshavyanka’ diesel-electric submarines by 2025, Russian Navy Deputy Commander-in-Chief Igor Mukhametshin said on Thursday.

The Navy’s deputy commander made this statement at the ceremony of floating out the first Project 636.3 submarine Petropavlovsk-Kamchatsky at the Admiralty Shipyard in St. Petersburg in northwest Russia. .

"I am confident that we will complete this series by 2025 and all the submarines will arrive at their permanent bases by that time," he said.

"In accordance with the defense minister’s instruction, all the stages … are clearly synchronized: training, the ship’s construction, the preparations for the transit, the arrival and the preparation of the infrastructure by that time," the Navy deputy chief said.

As Admiralty Shipyard CEO Alexander Buzakov said earlier on Thursday, all the Project 636.3 submarines will be built by 2022.

The Project 636.3 (‘Varshavyanka’) is referred to the third generation of diesel-electric submarines. The submarines of this type have been designed by the Rubin Central Design Bureau. They develop a speed of up to 20 knots, have sea endurance of 45 days and a crew of 52 men. They can dive to a depth of about 300 meters. The submarines of this class displace over 2,000 tonnes in their surface position and about 4,000 tonnes under the water. Varshavyanka-class subs are armed with Kalibr cruise missiles.

The first series of six submarines for the Black Sea Fleet was under construction from 2010 to 2016. The first two subs for the Pacific Fleet have been named the Petropavlovsk-Kamchatsky and the Volkhov.

Project 636 submarines are considered to be the most noiseless among Russian conventional subs. They have been dubbed the ‘Black Hole’ for their unique quietness. They are also furnished with modern radar and communications systems, sonars and 533mm torpedoes.
